In the Apocalypse, I Make the Dragon Nation the Supreme Power

[Invincible + livestreaming + national destiny + apocalyptic game + feel-good story + ruthless + keep a low profile] The National Destiny Apocalyptic Game has arrived. One person from each country is chosen at random to take part. If they survive, their country receives rewards. If they die, their country will suffer a disaster. Once a country's player death toll reaches 100, that country will disappear completely. Su Yan is chosen as the Dragon Kingdom's 100th player. After other countries join forces to hinder him, he unlocks the Doraemon template and successfully overcomes the crisis. Every day, he can draw an item. Using it earns him a reward. He successfully uses the item [Stone Hat] and tricks the Sakura Country player into a fatal trap. He successfully uses the item [Stun Gun] and easily turns the tables on the Korean player. He successfully uses the item [Gourmet Tablecloth] and enjoys hot pot among the ruins. Viewers from other countries are losing it! He successfully uses the item [Big Light] and steps on a boss who had grown to enormous size, killing it in one go. Viewers from other countries are completely bewildered. Congratulations! The player feature has been unlocked. Choose a female companion from among billions of races. Su Yan: Th-this... who should I choose?
